Abstract
Hydraulic excavator energy-saving is important to relieve source shortage and protect environment. This paper mainly discusses the energy saving for the hybrid hydraulic excavator. By analyzing the excess energy of three hydraulic cylinders in the conventional hydraulic excavator, a new boom potential energy recovery system is proposed. At last, the model of the proposed system has been built by AMESim. The simulation result shows that the proposed boom potential energy recovery system has a high energy saving efficiency.
